[00:00:01]The remainder of the Wilkins

威尔金斯的剩余部分

[00:02:15]looks set to break apart soon.

好似即将分崩离析

[00:04:41]It's the latest ice shelf

一道洋流向南漂流

[00:10:04]to disintegrate in a wave that's been travelling southwards,

一路上使新近形成的冰架破裂

[00:13:55]playing a major role in the loss of ice from the Peninsula.

这种作用是造成半岛冰雪流失的主要原因

[00:19:19]Next in line, and already weakening in places, are the ice shelves

接下来便轮到已很脆弱的冰架

[00:24:07]that hold back Antarctica's gigantic continental ice sheet.

这些冰架可防止南极巨大的冰原滑入海中

[00:28:53]And it would only take a small corner of this

每次崩裂的只是冰原一角

[00:32:24]to slide into the sea

不知不觉陷入大海

[00:34:12]to have major global consequences.

却能带来严重的全球效应

[00:36:26]We've only started to see

我们最近才刚看到

[00:41:23]changes in the Arctic and Antarctic recently.

北极和南极的变化

[00:44:32]So, it's hard to predict exactly

所以很难准确预言

[00:46:17]what impact these changes will have.

这些改变带来的影响

[00:48:52]But we can see for ourselves that these places are changing

但我们正目睹这些地区的改变

[00:52:48]and on a scale that is hard to ignore.

其规模无法忽视

[00:58:27]The Poles, North and South, may seem very remote,

南北两极看似地处偏远

[01:03:11]but what is happening here

但这里发生的事情

[01:05:11]is likely to have a greater effect upon us

对我们产生的影响

[01:08:41]than any other aspect of global warming.

可能远大于全球变暖的其他方面

[01:12:17]If the Arctic sea ice continues to disappear,

如果北极海冰继续融化

[01:15:32]it will drive up the planet's temperature more quickly.

地球气温升高的速度会更快

[01:19:09]And the melting ice sheets

到本世纪末 融化的冰原

[01:20:31]could contribute to a sea level rise of a metre,

能使海平面上升一米

[01:23:55]enough to threaten the homes of millions of people

足以威胁全世界沿海地区

[01:27:06]around the world's coasts by the end of the century.

数百万人的家庭

[01:32:06]We've seen that the animals

我们看见

[01:33:37]are already adapting to these changes,

动物已经在适应这些变化

[01:36:24]but can we respond to what is happening now to the frozen planet?

但我们能对冰冻星球的现象作出响应吗
